About These Birds
Long-tailed Wood-partridge
A medium-sized New World quail (~385 g) of family Odontophoridae, with a long tail distinguishing it from related species. Endemic to Mexican highland forests, inhabiting cloud forest, pine-oak woodland, and humid mountain forest above 1,500 m. Feeds on seeds, plant material, and insects on the forest floor. Least Concern; restricted to Mexican mountains but common in suitable habitat.
Nahan's Partridge
A small partridge (~280 g) of family Odontophoridae, dark reddish-brown with black barring. Endemic to lowland primary rainforest in Uganda and the Democratic Republic of Congo. Highly terrestrial, foraging on the forest floor for seeds, berries, and invertebrates. Vulnerable; requires intact primary forest and is threatened by widespread logging and agricultural conversion in Central Africa.
